 Uses latest generation geophysical mapping techniques to map the subsoil. Geophysics is a non-invasive soil survey technique that allows rapid mapping of large areas and reduces the risk of buried vectors being lost.
With more than 20 years of experience including 5 years in UK; Our offer of markets concerns the fields of defense, engineering (geotechnical), construction, environment, and energy; Frequently applied to geophysical exploration, Uses a planel of tools
 and techniques for identifying / mapping / profiling underground vectors such as mineral bodies, artificial rock heads, archaeological remains, contaminated or polluted areas, areas polluted by unexploded ordnance.
In geotechnics to characterize the soil / structure interaction or the sizing of work.

                                                                          Why choose and use geophysics?
Today, geophysical measurements should be included in most soil studies for construction, civil engineering and mineral exploration projects. At present, the use of geophysics is often the only way to obtain total ground coverage to ensure perfect identification and imagery of the research vectors before a work that is most invasive.

                                                                                           Low cost 
Geophysical measurements offer excellent value-for-money ratios over normal site investigation techniques. The accuracy of the information gained, coupled with the reduced cost of an invasive, optimal design follow-up survey, far exceeds the initial outlay.
                                                                                     Rapid Coverage
Up to 2 to 6 hectares of land can usually be surveyed in one day on an engineering project and up to 6 hectares if the target is minerals. it is possible to acquire up to 5 km according to the method. we can provide preliminary results of on-site anomaly locations (subject to in situ final data processing and analysis). All our studies are adjusted to the coordinates of the national grid or the grid of the local site, which makes the positioning of the anomalies simple and very precise.

                                                                              Little or no surface disturbance 
Geophysical surveys can be done in urban areas, highways or landscape environments without disturbing the surface.
